On the left side everything necessary: rivets and pop riveter, and
rivet test structure. The structure is a pair of aluminum sheet
that can be riveted in single or double shear. 7075 alloy
is used, so the sheets live a little longer.

The mid diagram shows what the DMS probe looks like (not
much to see though).

The right side shows the winch. This is
a dirt-cheap garage winch with a brake. The brake
is the most important part of the test rig: it ensures
a constant load when necessary (for calibration!). Just
stop the motor, and the brake will do the rest.
